Rayyan

What is Rayyan?

Rayyan is a research collaboration platform built for literature reviews and systematic reviews. You create a review, import references from databases in formats such as RIS, BibTeX, CSV and PDF, remove exact and near-duplicate records, and then screen each reference as Include, Exclude or Maybe. As you decide, Rayyan learns from your choices and ranks unscreened references by relevance. Teams can invite collaborators and use blind mode so reviewers do not see each other's decisions. Later steps cover data extraction, risk of bias assessment and export, plus a PRISMA flow diagram on paid plans. The company says more than 1 million researchers across 30,000 institutions use it. Individual plans start free with three active reviews, while Essential and Advanced are billed quarterly and institutional plans are arranged through sales.
